Men, use it to your advantage.
To date girls age 21-26, be the wild and crazy fun guy, NEVER put your heart in it and you do great.
To date girls age 27-30, talk about how you're ready to have a family and settle down, tired of the scene, just looking for someone sweet who is a freak in the bed. Use a condom, she might not.
To date girls age 31-35, you're the quickie rebound from her guy leaving, toddlers in the next room, messy time to probably avoid. hormone city.
To date girls age 35+, just have your shit together and be very honest, very up front. They'll smell your bullshit. Just say "i want to get laid" and you will.
Avoid all girls 18-20. Lazy fish in bed, thinks they're the shit, and drama too much.
